I'm trying to write a method that will convert a NSString containing a
file system URL to an FSRef with the following code
- (FSRef)stringToFSRef: (NSString*)filePath {
FSRef output;
CFStringRef cfFilePath = CFStringCreateWithCString(NULL, [filePath
cString], (CFStringEncoding)8);
CFURLRef url = CFCreateURLWithString(NULL, cfFilePath, NULL);
CFURLGetFSRef(url, &output);
return output;
}
CFStringRef and NSString are tool-free bridged
you can do this:
CFURLRef url = CFCreateURLWithString(kCFAllocatorDefault,
(CFStringRef)filePath, NULL);
And you must release it when done (even with GC)
CFRelease(url);
and NSURL and CFURL are tool free bridged, so can do this:
CFURLGetFSRef((CFURLRef)[NSURL URLWithString:filePath], &output);
